INDIANAPOLIS, Ind. — Navistar International introduced a 4×4 TerraStar and a showcased a full range of alternative fuel vehicles at this week’s Work Truck Show.

The 4×4 TerraStar broadens the applicability of International’s most recent truck offering, first introduced at last year’s Work Truck Show in a 4×2 configuration. Since launching the TerraStar last year, Navistar says it has received more than 2,000 orders for the Class 4/5 truck.

“With the addition of a 4×4 model, simply put, the International TerraStar is unmatched in the industry,” said Jim Hebe, Navistar’s senior vice-president, North American sales operations. “The design and durability of TerraStar is influenced by our entire line-up of commercial trucks, sharing the same rugged, durable, and hardworking DNA that’s made us an industry leader.”

Navistar also highlighted its range of alternative fuel vehicles, including the all-electric Class 2-3c eStar. The eStar has a range of 100 miles per charge and takes six to eight hours to recharge. It can carry payloads of up to two tonnes and produces no tailpipe emissions.

On the heavier side, Navistar offers the International DuraStar Hybrid, which it says can save fuel to the tune of 60% in utility-type applications.

Navistar also said it would be expanding its line of natural gas-powered trucks and at the show it featured an NG-fueled International WorkStar. The truck was powered by a DT-466 natural gas engine that can be configured to run off either liquefied or compressed natural gas.

Hebe said International will soon offer natural gas across its entire product line.

“And this isn’t just going out and grabbing the industry standard natural gas engine and putting it in our product,” he said during a press conference. “This is looking at our entire engine line and developing technology across our entire line, the DT and in the MaxxForce 11 and 13, in CNG and LNG, in single fuel and potentially dual fuel, offering our customers a full range of natural gas products from the MaxxForce DT right through the MaxxForce 13.”

Natural gas is already available in International WorkStar and DuraStar trucks powered by the DT engine, Hebe noted, and later in the year MaxxForce 9s and 10s will also be available in NG configurations.

“We are extremely excited about natural gas and where that’s going to take us,” Hebe said.

Hebe said he wasn’t going to get into the Advanced EGR vs SCR debate, but when asked point blank, he reiterated that he feels liquid urea-based SCR is doomed.

“We said all along that our belief was that a liquid-based SCR would be obsolete by the time we ran out of credits and I would reaffirm today that there are technologies out there a year or two from now that will make SCR, if not obsolete, certainly a second choice,” he said.

Hebe said Navistar submitted a MaxxForce 13 to the EPA for certification at 0.2 grams NOx per brake hp/hr a couple weeks ago, but will continue to use credits until they run out.
